  • Access Configuration Page of Modem (in bridge mode) through router

    - by Ujjwal Singh
    Given the Network Configuration: Internet (121.243.x.y/27) | (121.243.x.z) Static : Public Global IP Modem Bridge Mode | WiMAX (192.168.1.1/24) +169.254.1.1/24 : Modem Configuration Page | (192.168.1.2) Router DLink DIR 615 | Ethernet + WiFi (192.168.0.1/24) | Local network (192.168.0.2) Workstation Ethernet | no WiFi Is there any way, maybe using Routing Tables, to access the Modem configuration page at 169.254.1.1 from my local network, using a Windows 7 PC? Note that the modem is currently able to display its configuration page at 169.254.1.1, i.e. even while it is in bridge mode.

  • Quick CPU ring mode protection question

    - by b-gen-jack-o-neill
    Hi, me again :) I am very curious in messing up with HW. But my top level "messing" so far was linked or inline assembler in C program. If my understanding of CPU and ring mode is right, I cannot directly from user mode app access some low level CPU features, like disabling interrupts, or changing protected mode segments, so I must use system calls to do everything I want. But, if I am right, drivers can run in ring mode 0. I actually don´t know much about drivers, but this is what I ask for. I just want to know, is learning how to write your own drivers and than call them the way I should go, to do what I wrote? I know I could write whole new OS (at least to some point), but what I exactly want to do is acessing some low level features of HW from standart windows application. So, is driver the way to go?

  • DrawImage in XP Mode or Remote Desktop

    - by simplecoder
    I'm displaying a PNG with a transparent background that looks good in Windows 7, but then I run my app in XP Mode or remote desktop to a Windows XP machine and the PNG looks incorrect. I noticed that if I disable "Integration Mode" or run the app on XP without remote desktop, the image looks fine. How do I get DrawImage to render the PNG correctly in XP Mode or remote desktop? Image inside Windows 7 Image inside XP Mode or remote desktop Here's my code: protected override void OnPaint(PaintEventArgs e) { Image image = Image.FromFile("hello.png", false); Bitmap bmp = new Bitmap(image); Rectangle destRect = new Rectangle(0, 0, image.Width, image.Height); e.Graphics.DrawImage(image, destRect, 0, 0, image.Width, image.Height, GraphicsUnit.Pixel); base.OnPaint(e); }

  • Sharepoint 2007: Edit vs Read Only Mode

    - by user29116
    Sorry about the title, dont' really know what it should be. If I open a doc in read only mode I'm able to press save and then it opens up a save as box and the default directory is the directory on the sharepoint server and if you press save you save it to the server. This actually makes the whole process not really "read only" mode since I could actually update the document. Is there a way to prevent this from happening so that if someone chooses read only there is no way possible to updload any changes back to the sharepoint site? Also, it has been suggested as a solution to get rid of the edit/read only option so that people have to check out the document. Is there a way to remove the edit/read only option on documents?

  • Let emacs choose mode conditionally when opening files

    - by artistoex
    I'm using the php debugger geben and nxhtml-mode -- my standard mode for editing php files. Unfortunately, these two modes don't mix well. Is it possible to configure emacs such a way that it enables nxhtml only conditionaly, when I open php files manually, but enables php-mode instead when the buffer is opened by geben?

    I'm trying to record internet radio while listen it. I use the following line, but comes to my attention that when I set the iradio-mode true some noises comes in the recorded file, not in the playback. Without iradio-mode, all is ok.

  • Virtualbox in Headless mode

    - by ask
    I used the virtual machines in virtualbox in a "headless" mode instead of a GUI mode. what are the advantages of using it in a headless mode?? by headless does it mean that the server doesnt have a keyboard or monitor attached or does it mean that no window will "pop up" , denoting that it is ON(or any other status), when a virtual machine is worked with? what exactly does it mean? pls reply...

  • Video streaming over multi display units

    - by ramdaz
    We have to share video across around 4/8 terminals at a public facility where we need to display live video from within the facility, as well as display messages(advertisements), and also play videos(not live) which need to be controlled centrally from another location. We can do central location handling over Internet, over ssh. What we want to do is connect cameras to a computer, and use the computer to display over multiple display units. We need to do live titling if possible. Once the live local telecast which usually takes about an hour or two a day, we would like to play other videos locally off the PC server. Preferably everything should run off Linux, since budgets are very constrained.... Addendum -- Its not over WAN, it's over a local area. I prefer not using LAN, we would rather use co-axial cable if possible. The reason is if it's LAN, I need some kind of an Networking device, at least a thin client

  • Debug.Assert Appears in Release Mode

    - by Ngu Soon Hui
    We all know that Debug.Assert will not be compiled into the dlls when compiled in release mode. But for some reason Debug.Assert did appear in the release version of a component I wrote. I suspect that I might have mess up my csproject setting. Any idea why Debug.Assert appears in release mode? P/S: I have double checked to make sure that I was really compiling in release mode before asking this question.

  • Repeating characters in VIM insert mode

    - by Cthutu
    Is there a way of repeating a character while in Vim's insert mode? For example, say I would like to insert 80 dashes, in something like emacs I would type: Ctrl+U 8 0 - The only way I know how to do it in VIM is to exit normal mode for the repeat argument, then go back into insert mode to type the dash, then exit to insert the actual dashes, AND then go back into insert mode to carry on typing. The sequence is a really long: <ESC> 8 0 a - <ESC> a It would be nice not to switch in and out of modes. Thanks

  • [org-mode]: repeating task in every Mon, Wed, Fri at 18:00, need help with sexp.

    - by zeroDivisible
    Hello, As I had written in title, I need a little help with improvement of this sexp: * TODO remeber about thingie. SCHEDULED: <%%(or (= 1 (calendar-day-of-week date)) (= 3 (calendar-day-of-week date)) (= 5 (calendar-day-of-week date)))> Now it shows itself in the following days, but I would like to change two things about it: How can I also schedule on specific hours (i.e. 18:00 - 20:00) in the following days How can I made this task repeat itself, just like it repeats itself with <2010-05-13 Wed +1w> (by repetition I mean something like it automatically logs the closing date and time and comes back to the TODO state). I will be grateful for any help. Best regards, Mike.

  • Port forwarding with router in bridged mode

    - by jipje44
    let say R1 and R2. R1 is in bridged mode and connected to R2. R2 is a dhcp server. To R2 is an internet camera connected. When i am on R2 and i do enter the ip of the camera then it will work without a problem. However i want to acces the camera from the outside. So in R2 i forwarded a port (done this one other networks without problems). However I can't connect from the outside. Can R1 blocking the port? I cant log in on R1 as long as it is in bridged mode.

  • Emacs stops taking input when a file has changed on disk [migrated]

    - by recf
    I'm using Emacs v24.3.1 on Windows 8. I had a file change on disk while I had an Emacs buffer open with that file. As soon as I attempt to make a change to the buffer, a message appears in the minibuffer. Fileblah.txt changed on disk; really edit the buffer? (y, n, r or C-h) I would expect to be able to hit r to have it reload the disk version of the file, but nothing happens. Emacs completely stops responding to input. None of the listed keys work, nor do any other keys as far as I can tell. I can't C-g out of the minibuffer. Alt-F4 doesn't work, not does Close window from the task bar. I have to kill the process from task manager. Anyone have any idea what I'm doing wrong here? In cases it's various modes not playing nice with each other, for reference, my init.el is here. Nothing complex. Here's the breakdown: better-defaults (ido-mode, remove menu-bar, uniquify buffer `forward, saveplace) recentf-mode custom frame title visual-line-mode require final newline and delete trailing whitespace on save Markdown mode with auto-mode-alist Flyspell with Aspell backend Powershell mode with auto-mode-alist Ruby auto-mode-alist Puppet mode with auto-mode-alist Feature (Gherkin) mode with auto-mode-alist The specific file was a markdown file with Github-flavored Markdown mode and Flyspell mode enabled.

  • How to display a hierarchical skill tree in php

    - by user3587554
    If I have skill data set up in a tree format (where earlier skills are prerequisites for later ones), how would I display it as a tree, using php? The parent would be on top and have 3 children. Each of these children can then have one more child so its parent would be directly above it. I'm having trouble figuring out how to add the root element in the middle of the top div, and the child of the children below each child of the root. I'm not looking for code, but an explanation of how to do it. My data in array form is this: Data: Array ( [1] => Array ( [id] => 1 [title] => Jutsu [description] => Skill that makes you awesomer at using ninjutsu [tiers] => 1 [prereq] => [image] => images/skills/jutsu.png [children] => Array ( [2] => Array ( [id] => 2 [title] => fireball [description] => Increase your damage with fire jutsu and weapons [tiers] => 5 [prereq] => 1 [image] => images/skills/fireball.png [children] => Array ( [5] => Array ( [id] => 5 [title] => pin point [description] => Increases jutsu accuracy [tiers] => 5 [prereq] => 2 [image] => images/skills/pinpoint.png ) ) ) [3] => Array ( [id] => 3 [title] => synergy [description] => Reduce the amount of chakra needed to use ninjutsu [tiers] => 1 [prereq] => 1 [image] => images/skills/synergy.png ) [4] => Array ( [id] => 4 [title] => ebb & flow [description] => Increase the damage of water jutsu, water weapons, and reduce the damage of jutsu and weapons that use water element [tiers] => 5 [prereq] => 1 [image] => images/skills/ebbandflow.png [children] => Array ( [6] => Array ( [id] => 6 [title] => IQ [description] => Decrease the time it takes to learn a jutsu [tiers] => 5 [prereq] => 4 [image] => images/skills/iq.png ) ) ) ) ) ) An example would be this demo image minus the hover stuff.

  • How to display Sharepoint Data in a Windows Forms Application

    - by Michael M. Bangoy
    In this post I'm going to demonstrate how to retrieve Sharepoint data and display it on a Windows Forms Application. 1. Open Visual Studio 2010 and create a new Project. 2. In the project template select Windows Forms Application. 3. In order to communicate with Sharepoint from a Windows Forms Application we need to add the 2 Sharepoint Client DLL located in c:\Program Files\Common Files\Microsoft Shared\Web Server Extensions\14\ISAPI. 4. Select the Microsoft.Sharepoint.Client.dll and Microsoft.Sharepoint.Client.Runtime.dll. (Your solution should look like the one below) 5. Open the Form1 in design view and from the Toolbox menu Add a Button, TextBox, Label and DataGridView on the form. 6. Next double click on the Load Button, this will open the code view of the form. Add Using statement to reference the Sharepoint Client Library then create two method for the Load Site Title and LoadList. See below:   using System; using System.Collections.Generic; using System.ComponentModel; using System.Data; using System.Drawing; using System.Linq; using System.Text; using System.Security; using System.Windows.Forms; using SP = Microsoft.SharePoint.Client;   namespace ClientObjectModel {     public partial class Form1 : Form     {         // url of the Sharepoint site         const string _context = "theurlofthesharepointsite";         public Form1()         {             InitializeComponent();         }         private void Form1_Load(object sender, EventArgs e)         {                    }         private void getsitetitle()         {             SP.ClientContext context = new SP.ClientContext(_context);             SP.Web _site = context.Web;             context.Load(_site);             context.ExecuteQuery();             txttitle.Text = _site.Title;             context.Dispose();         }                 private void loadlist()         {             using (SP.ClientContext _clientcontext = new SP.ClientContext(_context))             {                 SP.Web _web = _clientcontext.Web;                 SP.ListCollection _lists = _clientcontext.Web.Lists;                 _clientcontext.Load(_lists);                 _clientcontext.ExecuteQuery();                 DataTable dt = new DataTable();                 DataColumn column;                 DataRow row;                 column = new DataColumn();                 column.DataType = Type.GetType("System.String");                 column.ColumnName = "List Title";                 dt.Columns.Add(column);                 foreach (SP.List listitem in _lists)                 {                     row = dt.NewRow();                     row["List Title"] = listitem.Title;                     dt.Rows.Add(row);                 }                 dataGridView1.DataSource = dt;             }                   }       private void cmdload_Click(object sender, EventArgs e)         {             getsitetitle();             loadlist();          }     } } 7. That’s it. Hit F5 to run the application then click the Load Button. Your screen should like the one below. Hope this helps.

  • Dynamically Changing the Display Names of Menus and Popups

    - by Geertjan
    Very interesting thing and handy to know when needed is the fact that "menuText" and "popupText" (from org.openide.awt.ActionRegistration) can be changed dynamically, via "putValue" as shown below for "popupText". The Action class, in this case, needs to be eager, hence you won't receive the object of interest via the constructor, but you can easily use the global Lookup for that purpose instead, as also shown below. import java.awt.event.ActionEvent; import java.text.DateFormat; import java.text.SimpleDateFormat; import javax.swing.AbstractAction; import org.netbeans.api.project.Project; import org.netbeans.api.project.ProjectInformation; import org.netbeans.api.project.ProjectUtils; import org.openide.awt.ActionID; import org.openide.awt.ActionReference; import org.openide.awt.ActionRegistration; import org.openide.util.Utilities; @ActionID( category = "Project", id = "org.ptt.DemoProjectAction") @ActionRegistration( lazy = false, displayName = "NOT-USED") @ActionReference(path = "Projects/Actions", position = 0) public final class DemoProjectAction extends AbstractAction{ private final ProjectInformation context; public DemoProjectAction() { putValue("popupText", "Select Me To See Current Time!"); context = ProjectUtils.getInformation( Utilities.actionsGlobalContext().lookup(Project.class)); } @Override public void actionPerformed(ActionEvent e) { refresh(); } protected void refresh() { DateFormat formatter = new SimpleDateFormat("HH:mm:ss"); String formatted = formatter.format(System.currentTimeMillis()); putValue("popupText", "Time: " + formatted + " (" + context.getDisplayName() +")"); } } Now, let's do something semi useful and display, in the popup, which is available when you right-click a project, the time since the last change was made anywhere in the project, i.e., we can listen recursively to any changes done within a project and then update the popup with the newly acquired information, dynamically: import java.awt.event.ActionEvent; import java.text.DateFormat; import java.text.SimpleDateFormat; import javax.swing.AbstractAction; import org.netbeans.api.project.Project; import org.netbeans.api.project.ProjectUtils; import org.openide.awt.ActionID; import org.openide.awt.ActionReference; import org.openide.awt.ActionRegistration; import org.openide.filesystems.FileAttributeEvent; import org.openide.filesystems.FileChangeListener; import org.openide.filesystems.FileEvent; import org.openide.filesystems.FileRenameEvent; import org.openide.util.Utilities; @ActionID( category = "Project", id = "org.ptt.TrackProjectTimerAction") @ActionRegistration( lazy = false, displayName = "NOT-USED") @ActionReference( path = "Projects/Actions", position = 0) public final class TrackProjectTimerAction extends AbstractAction implements FileChangeListener { private final Project context; private Long startTime; private Long changedTime; private DateFormat formatter; public TrackProjectTimerAction() { putValue("popupText", "Enable project time tracker"); this.formatter = new SimpleDateFormat("HH:mm:ss"); context = Utilities.actionsGlobalContext().lookup(Project.class); context.getProjectDirectory().addRecursiveListener(this); } @Override public void actionPerformed(ActionEvent e) { startTimer(); } protected void startTimer() { startTime = System.currentTimeMillis(); String formattedStartTime = formatter.format(startTime); putValue("popupText", "Timer started: " + formattedStartTime + " (" + ProjectUtils.getInformation(context).getDisplayName() + ")"); } @Override public void fileChanged(FileEvent fe) { changedTime = System.currentTimeMillis(); formatter = new SimpleDateFormat("mm:ss"); String formattedLapse = formatter.format(changedTime - startTime); putValue("popupText", "Time since last change: " + formattedLapse + " (" + ProjectUtils.getInformation(context).getDisplayName() + ")"); startTime = changedTime; } @Override public void fileFolderCreated(FileEvent fe) {} @Override public void fileDataCreated(FileEvent fe) {} @Override public void fileDeleted(FileEvent fe) {} @Override public void fileRenamed(FileRenameEvent fre) {} @Override public void fileAttributeChanged(FileAttributeEvent fae) {} }

  • Change style display for cells with Javascript

    - by Ronny
    Hi, I want to do something like this: user selects one radio button (lock,delete or compare). I want to show to him only the relevant column from the table. (each option has different column). The table is ajax. I guess i need to change the display style for every cell but i don't know how. Here is example: Here i want to change the display of the cells function ButtonForTbl(value) { var x=document.getElementById("audithead").rows[0].cells; if (value == "lock"){ document.getElementById('lock').checked = true; //something like for(...)lockCell.style.display='' //something like for(...)deleteCell.style.display='none' //something like for(...)compareCell.style.display='none' } else if(value == "delete"){ document.getElementById('delete').checked = true; //something like for(...)lockCell.style.display='none' //something like for(...)deleteCell.style.display='' //something like for(...)compareCell.style.display='none' } else{ document.getElementById('compare').checked = true; } } I guess i need something like that: for (i = 0; i < deleteCell.length; i++) deleteCell[i].style.display='' = true ; The table: oCell = oRow.insertCell(-1); oCell.setAttribute('id','comCell' ); oCell.setAttribute('align', 'center'); oCell.innerHTML = "<input type='checkbox' id='com' value='"+ ind + "'name='com[]'>"; oCell = oRow.insertCell(-1); oCell.setAttribute('id','lockCell' ); oCell.setAttribute('align', 'center'); oCell.innerHTML = "<input type='checkbox' id='lock' value='"+ ind + "'name='lock[]'>"; Radio buttons: <input type="radio" value="compare" id="compare" name="choose" onclick="ButtonForTbl(this.value)"/> Compare&nbsp; <input type="radio" value="delete" id="delete" name="choose" onclick="ButtonForTbl(this.value)"/> Delete&nbsp; <input type="radio" value="lock" id="lock" name="choose" onclick="ButtonForTbl(this.value)"/> Lock<br/> The table html: <table class="auditable"> <thead id="audithead"> <tr><td></td></tr> </thead> <tbody id="auditTblBody"> </tbody> </table> EDIT: Full row is like that: <tr> <td align="center" id="lockCell" style="display: none;"> <input type="checkbox" onclick="" name="lock[]" value="1500" id="lock"></td> <td align="center" id="delCell" style="display: none;"> <input type="checkbox" name="del[]" value="1500"></td> <td align="center" id="comCell"> <input type="checkbox" onclick="setChecks(this)" name="com[]" value="1500" id="com"></td> <td width="65px">100% 1/1</td><td width="105px">2011-01-10 17:47:37</td> </tr> Thank you so much!

  • openGL migration from SFML to glut, vertices arrays or display lists are not displayed

    - by user3714670
    Due to using quad buffered stereo 3D (which i have not included yet), i need to migrate my openGL program from a SFML window to a glut window. With SFML my vertices and display list were properly displayed, now with glut my window is blank white (or another color depending on the way i clear it). Here is the code to initialise the window : int type; int stereoMode = 0; if ( stereoMode == 0 ) type = GLUT_DOUBLE | GLUT_RGB | GLUT_DEPTH; else type = GLUT_DOUBLE | GLUT_RGB | GLUT_DEPTH | GLUT_STEREO; glutInitDisplayMode(type); int argc = 0; char *argv = ""; glewExperimental = GL_TRUE; glutInit(&argc, &argv); bool fullscreen = false; glutInitWindowSize(width,height); int win = glutCreateWindow(title.c_str()); glutSetWindow(win); assert(win != 0); if ( fullscreen ) { glutFullScreen(); width = glutGet(GLUT_SCREEN_WIDTH); height = glutGet(GLUT_SCREEN_HEIGHT); } GLenum err = glewInit(); if (GLEW_OK != err) { fprintf(stderr, "Error: %s\n", glewGetErrorString(err)); } glutDisplayFunc(loop_function); This is the only code i had to change for now, but here is the code i used with sfml and displayed my objects in the loop, if i change the value of glClearColor, the window's background does change color : glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT); glClearColor(255.0f, 255.0f, 255.0f, 0.0f); glLoadIdentity(); sf::Time elapsed_time = clock.getElapsedTime(); clock.restart(); camera->animate(elapsed_time.asMilliseconds()); camera->look(); for (auto i = objects->cbegin(); i != objects->cend(); ++i) (*i)->draw(camera); glutSwapBuffers(); Is there any other changes i should have done switching to glut ? that would be great if someone could enlighten me on the subject. In addition to that, i found out that adding too many objects (that were well handled before with SFML), openGL gives error 1285: out of memory. Maybe this is related. EDIT : Here is the code i use to draw each object, maybe it is the problem : GLuint LightID = glGetUniformLocation(this->shaderProgram, "LightPosition_worldspace"); if(LightID ==-1) cout << "LightID not found ..." << endl; GLuint MaterialAmbientID = glGetUniformLocation(this->shaderProgram, "MaterialAmbient"); if(LightID ==-1) cout << "LightID not found ..." << endl; GLuint MaterialSpecularID = glGetUniformLocation(this->shaderProgram, "MaterialSpecular"); if(LightID ==-1) cout << "LightID not found ..." << endl; glm::vec3 lightPos = glm::vec3(0,150,150); glUniform3f(LightID, lightPos.x, lightPos.y, lightPos.z); glUniform3f(MaterialAmbientID, MaterialAmbient.x, MaterialAmbient.y, MaterialAmbient.z); glUniform3f(MaterialSpecularID, MaterialSpecular.x, MaterialSpecular.y, MaterialSpecular.z); // Get a handle for our "myTextureSampler" uniform GLuint TextureID = glGetUniformLocation(shaderProgram, "myTextureSampler"); if(!TextureID) cout << "TextureID not found ..." << endl; glActiveTexture(GL_TEXTURE0); sf::Texture::bind(texture); glUniform1i(TextureID, 0); // 2nd attribute buffer : UVs GLuint vertexUVID = glGetAttribLocation(shaderProgram, "color"); if(vertexUVID==-1) cout << "vertexUVID not found ..." << endl; glEnableVertexAttribArray(vertexUVID); glBindBuffer(GL_ARRAY_BUFFER, color_array_buffer); glVertexAttribPointer(vertexUVID, 2, GL_FLOAT, GL_FALSE, 0, 0); GLuint vertexNormal_modelspaceID = glGetAttribLocation(shaderProgram, "normal"); if(!vertexNormal_modelspaceID) cout << "vertexNormal_modelspaceID not found ..." << endl; glEnableVertexAttribArray(vertexNormal_modelspaceID); glBindBuffer(GL_ARRAY_BUFFER, normal_array_buffer); glVertexAttribPointer(vertexNormal_modelspaceID, 3, GL_FLOAT, GL_FALSE, 0, 0 ); GLint posAttrib; posAttrib = glGetAttribLocation(shaderProgram, "position"); if(!posAttrib) cout << "posAttrib not found ..." << endl; glEnableVertexAttribArray(posAttrib); glBindBuffer(GL_ARRAY_BUFFER, position_array_buffer); glVertexAttribPointer(posAttrib, 3, GL_FLOAT, GL_FALSE, 0, 0); glBindBuffer(GL_ELEMENT_ARRAY_BUFFER, elements_array_buffer); glDrawElements(GL_TRIANGLES, indices.size(), GL_UNSIGNED_INT, 0); GLuint error; while ((error = glGetError()) != GL_NO_ERROR) { cerr << "OpenGL error: " << error << endl; } disableShaders();

My code is the following : public partial class Form1 : Form { public OleDbConnection datCon; public string MyDataFile; public ArrayList tblArray; public ArrayList fldArray; public Form1() { InitializeComponent(); lvData.Clear(); lvData.View = View.Details; lvData.LabelEdit = false; lvData.FullRowSelect = true; lvData.GridLines = true; } private void DataConnection() { MyDataFile = Application.StartupPath + @"\studenti.mdb"; string MyCon = @"provider=microsoft.jet.oledb.4.0;data source=" + MyDataFile; try { datCon = new OleDbConnection(MyCon); } catch (Exception ex) { MessageBox.Show(ex.Message); } FillTreeView(); } private void GetTables(OleDbConnection cnn) { try { cnn.Open(); DataTable schTable = cnn.GetOleDbSchemaTable(OleDbSchemaGuid.Tables, new Object[] { null, null, null, "TABLE" }); tblArray = new ArrayList(); foreach (DataRow datrow in schTable.Rows) { tblArray.Add(datrow["TABLE_NAME"].ToString()); } cnn.Close(); } catch (Exception ex) { MessageBox.Show(ex.Message); } } private void GetFields(OleDbConnection cnn, string tabNode) { string tabName; try { tabName = tabNode; cnn.Open(); DataTable schTable = cnn.GetOleDbSchemaTable(OleDbSchemaGuid.Columns, new Object[] { null, null, tabName }); fldArray = new ArrayList(); foreach (DataRow datRow in schTable.Rows) { fldArray.Add(datRow["COLUMN_NAME"].ToString()); } cnn.Close(); } catch (Exception ex) { MessageBox.Show(ex.Message); } } private void FillTreeView() { tvData.Nodes.Clear(); tvData.Nodes.Add("Database"); tvData.Nodes[0].Tag = "RootDB"; GetTables(datCon); // add table node for (int i = 0; i < tblArray.Count; i++) { tvData.Nodes[0].Nodes.Add(tblArray[i].ToString()); tvData.Nodes[0].Nodes[i].Tag = "Tables"; } // add field node for (int i = 0; i < tblArray.Count; i++) { GetFields(datCon, tblArray[i].ToString()); for (int j = 0; j < fldArray.Count; j++) { tvData.Nodes[0].Nodes[i].Nodes.Add(fldArray[j].ToString()); tvData.Nodes[0].Nodes[i].Nodes[j].Tag = "Fields"; } } this.tvData.ContextMenuStrip = contextMenuStrip1; contextMenuStrip1.ItemClicked +=contextMenuStrip1_ItemClicked; } public void FillListView(OleDbConnection cnn, string tabName) { OleDbCommand cmdRead; OleDbDataReader datReader; string strField; lblTableName.Text = tabName; strField = "SELECT * FROM [" + tabName + "]"; // Initi cmdRead obiect cmdRead = new OleDbCommand(strField, cnn); cnn.Open(); datReader = cmdRead.ExecuteReader(); // fill ListView while (datReader.Read()) { ListViewItem objListItem = new ListViewItem(datReader.GetValue(0).ToString()); for (int c = 1; c < datReader.FieldCount; c++) { objListItem.SubItems.Add(datReader.GetValue(c).ToString()); } lvData.Items.Add(objListItem); } datReader.Close(); cnn.Close(); } private void ViewToolStripMenuItem_Click(object sender, EventArgs e) { DataConnection(); } public void tvData_AfterExpand(object sender, System.Windows.Forms.TreeViewEventArgs e) { string tabName; int fldCount; if (e.Node.Tag.ToString() == "Tables") { fldCount = e.Node.GetNodeCount(false); //column headers. int n = lvData.Width; double wid = n / fldCount; // width columnn for (int c = 0; c < fldCount; c++) { lvData.Columns.Add(e.Node.Nodes[c].Text, (int)wid, HorizontalAlignment.Left); } // gett table name tabName = e.Node.Text; FillListView(datCon, tabName); } } public void button1_Click(object sender, EventArgs e) { //TO DO?? } } I have a treeview populated with tables (nodes) from my database, and a listview which is populated with the data from my tables when I click on a table. As you can see I have a button1 on my form. When I click it I want it to display to me the structure of the table I selected in my treeview (a treeview node). Not too many details, just the name of the columns in my table, type of columns, primary keys. I've tried to follow many tutorials but I can t seem to manage it.
